introduction: objective: this study aimed to assess the possible variations in root canal anatomy and topography of the apices of first and second maxillary molars. materials and methods: a total of 67 first and second maxillary permanent molars were collected. access cavity was prepared and 2% methylene blue was injected. the teeth were demineralized by 5% nitric acid and cleared with methyl s...

introduction: the complexity of the root canal system presents a challenge for the practitioner. this systematic review evaluated the papers published in the field of root canal anatomy and configuration of the root canal system in permanent maxillary second molars. methods and materials: all articles related to the root morphology and root canal anatomy of the permanent maxillary second molars...

The maxillary first molar usually has single palatal root. Incidence rate of maxillary first molar with two palatal roots is especially rare. We reported a case of young maxillary first molar with two palatal roots in this article. Anatomic characteristic of permanent maxillary molar is generally described as a group of teeth with three roots, one palatal and two buccalbut the root canal system...

autogenous tooth transplantation (att) is a simple and reasonable choice for replacing the missing teeth when a proper donor tooth is available. this report presents a case of successful att of a maxillary right third molar for replacement of mandibular right second molar with a concomitant endodontic-periodontal disease. the mandibular second molar was believed to be hopeless due to a severe d...

AIM The purpose of this report is to present two cases of totally impacted maxillary deciduous molars, considered a rarity in dental practice. BACKGROUND Primary tooth impaction is quite rare during the development of primary dentition. Various factors contribute to the impaction of a deciduous tooth, including anklyosis, congenitally missing permanent teeth, defects in the periodontal membra...

The objective of this study is to determine the prevalence of expression and bilateralism of two dental morphological traits in contemporary Jordanians: The hypocone reduction trait on the maxillary second permanent molar and Carabelli's trait on maxillary permanent first and second molars. Furthermore, inter-trait correlation and the relationship of Carabelli's traits with upper first molar di...

The purpose of this study was to elucidate a possible association between ectopic first molar eruption causing root resorption on the distal root of the primary maxillary second molar, and ectopic canine eruption causing root resorption on the permanent maxillary incisors. The subjects consisted of 30 patients, 22 females and eight males in the age range 8.3-15.0 years in whom root resorption o...
